Patient tolerability during office cystoscopy and bladder tumor cauterization: a multivariate analysis of risk factors.	OBJECTIVE: Cystoscopy and cauterization performed in the operating room is expensive and exposes patients to anesthesia risks. Patient tolerability during office cystoscopy and cauterization is critical to the office management of bladder cancer (BC) and other urologic diseases. We evaluated the risk factors for pain of flexible cystoscopy in the office-setting with emphasis on a sub-group of BC patients who underwent cauterization. MATERIALS AND METHODS: Retrospective analyses of 110 anonymous patient surveys completed after cystoscopy and/or cauterization. Survey information included age, gender, indication for cystoscopy, number of prior cystoscopies, number of prior office-based cauterizations, anxiety prior/during cystoscopy, and pain during cystoscopy and/or cauterization. Univariate/multivariate and linear-regression analyses were performed to evaluate the association of pain with clinical parameters. RESULTS: Average pain during cystoscopy (1.75 ± 1.331) was not significantly different when cauterization was also performed (2.37 ± 2.214) (p < 0.001) (p = 0.2840). Patients in the lower age group (<66 years) indicated higher anxiety levels (p = 0.0005), more pain at cystoscopy (P = 0.004) and cauterization (p < 0.001). Although the patients' overall anxiety level was low (1-3/10), it was associated with some pain during cystoscopy (p = 0.0005) and cauterization (p < 0.000). In multivariate analysis, anxiety was the only independent predictor of pain during cystoscopy (p = 0.03, OR: 6.52,95% CI: 1.2-35.6) and cauterization (p = 0.0012, OR: 3.4, 95%CI: 1.6-7.0). In BC patients, pain scores during cystoscopy and cauterization were not significantly different (p = 0.4772) but associated with anxiety. CONCLUSION: Office-based cystoscopy and cauterization are tolerable with minimal pain. Higher pain levels during cystoscopy were associated with procedure anxiety, and pain during cauterization was associated with procedure anxiety and younger age. Younger and more anxious patients may need more counseling before cystoscopy.	bladder
Atezolizumab for the treatment of advanced recurrent basal cell carcinoma and urothelial carcinoma of bladder: a case report.	BACKGROUND: The use of checkpoint inhibitors has become increasingly important in the treatment of different cancers, including advanced muscle-invasive urothelial cancer and even in basal cell carcinoma. We present the case of a patient with advanced basal cell carcinoma and metastatic muscle-invasive urothelial cancer, who was treated with the programmed death-ligand 1 inhibitor, atezolizumab for both cancers. CASE PRESENTATION: A 72-year-old Caucasian female patient, with a history of smoking without any comorbidities developed periocular basal cell carcinoma, which was surgically removed but relapsed 4 years later. Surgical excision was carried out twice, but with positive margins, therefore definitive radiotherapy was given. Subsequently, the patient developed non-muscle-invasive papillary urothelial carcinoma, which was removed by transurethral resection. Follow-up was irregular owing to the patient's inadequate compliance, and within 2 years, the patient's cancer relapsed and histology confirmed muscle-invasive urothelial carcinoma. Definitive radiochemotherapy was not accepted by the patient. Meanwhile, the patient's basal cell carcinoma had also progressed, despite receiving vismodegib therapy. Therefore, the patient was administered epirubicin-cisplatin. Having reached the maximum cumulative dose of epirubicin, treatment with this chemotherapeutic agent could not be continued. The patient developed bladder cancer metastasis in her left suprainguinal lymph nodes. Owing to the presence of both types of tumors, programmed death-ligand 1 inhibitor atezolizumab treatment was chosen. In just over 1 year, the patient received 17 cycles of atezolizumab altogether, which was tolerated well without any adverse or side effects. Follow-up imaging scans indicated complete remission of the metastatic bladder cancer and stable disease of the basal cell carcinoma. The patient subsequently passed away in hospital due to a complication of COVID-19 infection. CONCLUSIONS: Our patient attained stable disease in advanced basal cell carcinoma and complete remission in metastatic muscle-invasive urothelial cancer after receiving programmed death-ligand 1 inhibitor, atezolizumab, therapy. To our knowledge, this is the first paper to report the use of programmed death-ligand 1 inhibitor, atezolizumab, as treatment for advanced basal cell carcinoma. This case may also be of interest for clinicians when treating patients with two synchronous cancers.	bladder
The targets of aspirin in bladder cancer: bioinformatics analysis.	BACKGROUND: The anti-carcinogenic properties of aspirin have been observed in some solid tumors. However, the molecular mechanism of therapeutic effects of aspirin on bladder cancer is still indistinct. We introduced a bioinformatics analysis approach, to explore the targets of aspirin in bladder cancer (BC). METHODS: To find out the potential targets of aspirin in BC, we analyzed direct protein targets (DPTs) of aspirin in Drug Bank 5.0. The protein-protein interaction (PPI) network and signaling pathway of aspirin DPTs were then analyzed subsequently. A detailed analysis of the KEGG (Kyoto Encyclopedia of Genes and Genomes) pathway has shown that aspirin is linked to BC. We identified overexpressed genes in BC comparing with normal samples by Oncomine and genes that interlinked with aspirin target genes in BC by STRING. RESULTS: Firstly, we explored 16 direct protein targets (DPT) of aspirin. We analyzed the protein-protein interaction (PPI) network and signaling pathways of aspirin DPT. We found that aspirin is closely associated with a variety of cancers, including BC. Then, we classified mutations in 3 aspirin DPTs (CCND1, MYC and TP53) in BC using the cBio Portal database. In addition, we extracted the top 50 overexpressed genes in bladder cancer by Oncomine and predicted the genes associated with the 3 aspirin DPTs (CCND1, MYC and TP53) in BC by STRING. Finally, 5 exact genes were identified as potential therapeutic targets of aspirin in bladder cancer. CONCLUSION: The analysis of relevant databases will improve our mechanistic understanding of the role of aspirin in bladder cancer. This will guide the direction of our next drug-disease interaction studies.	bladder
Fibroblast Common Serum Response Signature-Related Classification Affects the Tumour Microenvironment and Predicts Prognosis in Bladder Cancer.	"Abnormal oncogenic signatures provide important clues regarding cancer prognosis and treatment. We analysed the variations in 189 oncogenic signature gene sets between normal and tumourous tissues from The Cancer Genome Atlas (TCGA) and found that the ""CSR_LATE_UP"" signature was the most upregulated oncogenic signature gene set in bladder cancer. Next, we developed a common serum response (CSR) risk score (CRS) model based on fibroblast CSR genes and systematically analysed the correlations of these genes or the CRSs with survival, previously reported molecular subtypes, clinicopathological features, cancer signalling pathways, chemotherapeutic responses, and the tumour microenvironment using TCGA and validation cohorts. The CRS could predict the malignant phenotype, chemotherapeutic efficacy, immune invasion, and disease prognosis. Inflammatory signalling pathways (e.g., inflammatory response, TNFA signalling via NFƘB, IFNα response, and IL2-STAT5 signalling) were markedly upregulated in patients with high CRS. Notably, the CSR-related gene ANLN was positively correlated with CD8(+) immune cell infiltration, PD-L1 expression, and sensitivity to PD-L1 inhibitors and could thus provide guidance for clinical immunotherapy. This study highlights the crucial role of the CSR signature in bladder cancer and provides a CRS model for accurate predictions of the disease prognosis and chemotherapy and immunotherapy responses."	bladder
Poor Prognosis With Intravesical Bacillus Calmette-Guérin History After Photodynamic Diagnosis-assisted Transurethral Resection Using 5-Aminolevulinic Acid.	BACKGROUND/AIM: Diagnostic efficacy and treatment outcome of orally administered 5 aminolevulinic acid (ALA) assessment for photodynamic diagnosis (PDD) in transurethral resection for non-muscle-invasive bladder cancer (NMIBC) in clinical practice. PATIENTS AND METHODS: A retrospective analysis was performed of 105 patients who underwent PDD transurethral resection using orally administered ALA and were pathologically diagnosed with Ta, T1, or Tis at the Ishikawa Prefectural Central Hospital from December 2018 to May 2022. RESULTS: Fluorescent light had a significantly higher sensitivity but a lower specificity in detecting carcinoma compared to white light (91.7% vs. 77.1%; p<0.05 and 43.0% vs. 85.2%; p<0.05, respectively), as well as in detecting carcinoma in situ lesions (80.4% vs. 28.6%; p<0.05 and 23.3% vs. 84.5%; p<0.05, respectively). The cumulative frequency of recurrence and progression 1 year after treatment were 26.3% and 12.3%, respectively. Multivariate analyses indicated that a Bacillus Calmette-Guérin (BCG) history instillation was an independent predictive factor for intravesical recurrence (hazard ratio=4.439; p=0.002) and disease progression (hazard ratio=8.534; p=0.005). The 1-year cumulative recurrence rates were 66.2% and 16.5%, respectively (p<0.001), and progression rates for patients with and without prior BCG intravesical instillation were 50.4% and 3.5%, respectively (p<0.001). CONCLUSION: Sufficient diagnostic accuracy and relatively good treatment outcome was shown in PDD-transurethral resection using ALA. However, prior BCG intravesical instillation for NMIBC patients was a poor prognostic factor of cancer recurrence and progression, and may be useful for clinicians in their postoperative follow-up.	bladder
Comprehensive Analysis of the Oncogenic Role of Targeting Protein for Xklp2 (TPX2) in Human Malignancies.	Mitosis and spindle assembly require the microtubule-associated protein Xenopus kinesin-like protein 2 (TPX2). Although TPX2 is highly expressed in several malignant tumor forms, little is known about its role in cancer. In this study, we performed the gene set enrichment analysis of TPX2 in 33 types of cancers and an extensive pan-cancer bioinformatic analysis using prognosis, tumor mutational burdens, microsatellite instability, tumor microenvironment, and immune cell infiltration data. According to the differential expression study, TPX2 was found to be overexpressed across all studied cancer types. Based on the survival analysis, increased TPX2 expression was associated with a poor prognosis for most cancers. The TPX2 expression level was confirmed to correlate with the clinical stage, microsatellite instability, and tumor mutational burden across all cancer types. Furthermore, TPX2 expression has been linked to tumor microenvironments and immune cell infiltration, particularly in bladder urothelial carcinoma, liver hepatocellular carcinoma, lung adenocarcinoma, stomach adenocarcinoma, and uterine corpus endometrial carcinoma. Finally, the gene set enrichment analysis implicated TPX2 in the regulation of aminoacyl tRNA biosynthesis, which is the most important tumor cell cycle signaling pathway. This comprehensive pan-cancer analysis shows that TPX2 is a prognostic molecular biomarker for most cancers and suggests its potential as an effective therapeutic target for the treatment of these diseases.	bladder
Quality improvement in managing patients with non-muscle-invasive bladder cancer by introducing a surgical checklist for transurethral resection of bladder tumor.	BACKGROUND: The quality of transurethral resection of bladder tumor (TURBT) markedly varies among surgeons and may have a considerable impact on treatment outcomes. The importance of a surgical checklist for TURBT has been suggested in order to standardize the procedure and improve surgical and oncological outcomes. In the present study, we verified the usefulness of a checklist for managing patients with non-muscle-invasive bladder cancer (NMIBC). METHODS: This retrospective study included 201 NMIBC patients diagnosed with Ta, T1, or Tis between October 2011 and February 2021. After September 2016, TURBT was performed with a checklist. We analyzed the intravesical recurrence-free survival (RFS) rate and the presence or absence of the detrusor muscle in resected specimens before and after the introduction of the checklist. Survival rates were compared using the Log-rank test. A multivariate analysis with Cox proportional hazards modeling was performed to verify risk factors for intravesical recurrence. RESULTS: Ninety-nine patients who underwent TURBT with the checklist (checklist group) were compared with 102 patients who underwent TURBT without the checklist (non-checklist group). When the analysis was narrowed down to 9 critical items, we observed a mean number of 9 documented items per operative report (98.0% completion) after implementation of the checklist. Two-year intravesical RFS rates in the checklist and non-checklist groups were 76.7 and 69.5%, respectively (p = 0.1059). The Cox proportional multivariate analysis showed that the rate of intravesical recurrence was slightly lower in the checklist group (hazard ratio 0.7376, 95% CI 0.4064-1.3388, P = 0.3170). CONCLUSION: The introduction of a checklist is recommended for the standardization of TURBT and increasing the quality of operative reporting, and it may also improve oncological outcomes.	bladder
Effect of Antacid Use on Immune Checkpoint Inhibitors in Advanced Solid Cancer Patients: A Systematic Review and Meta-analysis.	The influence of antacids use on immune checkpoint inhibitor (ICI) efficacy remains unclear. A systematic review and meta-analysis was performed to evaluate the effect of proton pump inhibitors (PPIs) and histamine-2-receptor antagonists (H2RAs) on ICI efficacy in advanced solid cancer patients. A systematic literature search in PubMed, EMBASE, and Web of Science was performed to retrieve studies investigating the effect of antacid use on ICI efficacy. Overall survival (OS), progression-free survival (PFS), objective response rate (ORR), and immune-related adverse events were measured using hazard ratios (HRs) or odds ratios (ORs). Thirty studies enrolling 16,147 advanced cancer patients receiving ICI treatment were included. The pooled analysis indicated that PPI use was associated with shorter OS (HR=1.40, 95% CI, 1.25-1.57) and PFS (HR=1.34, 95% CI, 1.19-1.52) in advanced cancer patients treated with ICIs. PPI use did not show effect on ORR or immune-related adverse event of advanced cancer patients receiving ICI treatment. OS, PFS, and ORR did not differ between H2RA users and non-H2RA users. In subgroup analyses, PPI use was associated with shorter OS and PFS in NSCLC and urothelial carcinoma patients and in patients treated with anti-programmed cell death 1 or anti-programmed cell death ligand 1 monotherapy. In addition, ICI efficacy was different in the antacid exposure time frame subgroups. In conclusion, PPI use has a negative effect on OS and PFS among advanced cancer patients receiving ICI treatment. PPIs should be cautiously administered among advanced cancer patients treated with ICI. The safety of H2RAs and the influence of H2RAs on ICI efficacy need further investigation.	bladder
SOX2 Promotes Invasion in Human Bladder Cancers through MMP2 Upregulation and FOXO1 Downregulation.	SOX2, a member of the SRY-related HMG-box (SOX) family, is abnormally expressed in many tumors and associated with cancer stem cell-like properties. Previous reports have shown that SOX2 is a biomarker for cancer stem cells in human bladder cancer (BC), and our most recent study has indicated that the inhibition of SOX2 by anticancer compound ChlA-F attenuates human BC cell invasion. We now investigated the mechanisms through which SOX2 promotes the invasive ability of BC cells. Our studies revealed that SOX2 promoted SKP2 transcription and increased SKP2-accelerated Sp1 protein degradation. As Sp1 is a transcriptionally regulated gene, HUR transcription was thereby attenuated, and, in the absence of HUR, FOXO1 mRNA was degraded fast, which promoted BC cell invasion. In addition, SOX2 promoted BC invasion through the upregulation of nucleolin transcription, which resulted in increased MMP2 mRNA stability and expression. Collectively, our findings show that SOX2 promotes BC invasion through both SKP2-Sp1-HUR-FOXO1 and nucleolin-MMP2 dual axes.	bladder
Response of the Urothelial Carcinoma Cell Lines to Cisplatin.	Cisplatin (CDDP)-based chemotherapy is the standard of care in patients with muscle-invasive bladder cancer. However, in a large number of cases, the disease becomes resistant or does not respond to CDDP, and thus progresses and disseminates. In such cases, prognosis of patients is very poor. CDDP manifests its cytotoxic effects mainly through DNA damage induction. Hence, response to CDDP is mainly dependent on DNA damage repair and tolerance mechanisms. Herein, we have examined CDDP response in a panel of the urothelial carcinoma cell (UCC) lines. We characterized these cell lines with regard to viability after CDDP treatment, as well as kinetics of induction and repair of CDDP-induced DNA damage. We demonstrate that repair of CDDP-induced DNA lesions correlates, at least to some extent, with CDDP sensitivity. Furthermore, we monitored expression of the key genes involved in selected DNA repair and tolerance mechanisms, nucleotide excision repair, homologous recombination and translesion DNA synthesis, and show that it differs in the UCC lines and positively correlates with CDDP resistance. Our data indicate that CDDP response in the UCC lines is dependent on DNA damage repair and tolerance factors, which may, therefore, represent valuable therapeutic targets in this malignancy.	bladder
Chronic Arsenic Exposure Upregulates the Expression of Basal Transcriptional Factors and Increases Invasiveness of the Non-Muscle Invasive Papillary Bladder Cancer Line RT4.	The bladder is a target organ for inorganic arsenic, a carcinogen and common environmental contaminant found in soil and water. Urothelial carcinoma (UC) is the most common type of bladder cancer (BC) that develops into papillary or non-papillary tumors. Papillary tumors are mostly non-muscle invasive (NMIUC), easier treated, and have a better prognosis. Urothelial carcinoma can be molecularly sub-typed as luminal or basal, with papillary tumors generally falling into the luminal category and basal tumors exclusively forming muscle invasive urothelial carcinomas (MIUC). It is unclear why some UCs develop more aggressive basal phenotypes. We hypothesized that chronic arsenic exposure of a papillary luminal bladder cancer would lead to the development of basal characteristics and increase in invasiveness. We treated the human papillary bladder cancer cell line RT4 with 1 µM arsenite (As(3+)) for twenty passages. Throughout the study, key luminal and basal gene/protein markers in the exposed cells were evaluated and at passage twenty, the cells were injected into athymic mice to evaluate tumor histology and measure protein markers using immunohistochemistry. Our data indicates that chronic As(3+)- treatment altered cellular morphology and decreased several luminal markers in cell culture. The histology of the tumors generated from the As(3+)-exposed cells was similar to the parent (non-treated) however, they appeared to be more invasive in the liver and displayed elevated levels of some basal markers. Our study demonstrates that chronic As(3+) exposure is able to convert a non-invasive papillary bladder cancer to an invasive form that acquires some basal characteristics.	bladder
A Pan-Cancer Analysis of Heat-Shock Protein 90 Beta1(HSP90B1) in Human Tumours.	BACKGROUND: HSP90B1, a member of the heat-shock protein 90 family, plays a vital role as a molecular chaperone for oncogenes and stimulates tumour growth. However, its role in various cancers remains unexplored. METHODS: Using the cancer genome atlas, gene expression omnibus the Human Protein Atlas databases and various other bioinformatic tools, this study investigated the involvement of HSP90B1 in 33 different tumour types. RESULTS: The over-expression of HSP90B1 generally predicted poor overall survival and disease-free survival for patients with tumours, such as adrenocortical carcinoma, bladder urothelial carcinoma, kidney renal papillary cell carcinoma, and lung adenocarcinoma. In this study, HSP90B1 was highly expressed in the majority of tumours. A comparison was made between the phosphorylation of HSP90B1 in normal and primary tumour tissues, and putative functional mechanisms in HSP90B1-mediated oncogenesis were investigated. Additionally, the mutation burden of HSP90B1 in cancer was evaluated along with the survival rate of patients with cancer patients. CONCLUSION: This first pan-cancer investigation reveals the oncogenic functions of HSP90B1 in various cancers.	bladder
Luminophore Chemistry for Detection of Urinary Bladder Cancer - Comparison to Cytology and Urinary Rapid Tests (BTA stat(®), NMP22(®) BladderChek(®) and UBC(®) Rapid Test).	BACKGROUND/AIM: New luminometric chelates were developed for the detection of urinary bladder cancer and compared to cytology and urinary rapid tests BTA stat(®), NMP22(®) BladderChek(®) and UBC(®) Rapid Test. MATERIALS AND METHODS: This single-center study analyzed urine from two different cohorts: Firstly, a retrospective pilot cohort (n=27) and secondly a prospective validation cohort (n=60) including patients with bladder cancer and healthy controls. The samples were studied with nine different terbium and europium chelates to detect cancer cases. After identification of an efficient luminophore in the first cohort, the second validation cohort was run with the selected chelates to re-evaluate the results and compare them with urinary rapid tests and cytology. RESULTS: The compared methods showed area under the curve (AUC) values ranging from 0.567 to 0.767. Tb(3+)-chelate-based assay detected high-grade cancer cases (p=0.035) with an AUC of 0.663. The Eu-probe signal level was higher in cancer cases of any grade than in healthy controls (p=0.001) with an AUC of 0.759. The Eu-probe had a sensitivity of 46.7% and a specificity of 100% in cancer detection. CONCLUSION: Evaluation of terbium and europium chelates for the detection of urinary bladder cancer showed highest specificity among all methods and improved overall performance (characterized by AUC) compared to commercial urine-based rapid tests and cytology. The Eu-probe has the potential to be clinically valuable in urine-based detection of bladder cancer, especially for high-grade cancer.	bladder
